clock - Computer Definition

An internal timing device. Using a quartz crystal, the CPU clock breathes life into the microprocessor by feeding it a constant flow of pulses. For example, a 200 MHz CPU receives 200 million pulses per second from the clock. A 2 GHz CPU gets two billion pulses per second. Similarly, in a communications device, a clock is used to set the transmission speed and may also be used to synchronize the pulses between sender and receiver.
A "real-time clock," also called the "system clock," keeps track of the time of day and makes this data available to the software. A "timesharing clock" interrupts the CPU at regular intervals and allows the operating system to divide its time between active users and/or applications. See per clock, clockless computing and MHz.

The CPU Clock

The quartz crystal generates continuous waves, which are converted into digital pulses.

There is smoke and grease there is the wrist exhaustion , there is laughter , there is the letter seized in the clock and the apple's tang, the river sliding along its banks. darker now than the sky descending a last time to scatter its diamonds into these black waters that contain the day that passed, the night to come.
